Narrative Opinion Summary
In this appellate case, Bruno Independent Living Aids, Inc., a manufacturer of stairlifts, challenged a decision by the United States District Court for the Western District of Wisconsin, which awarded attorney fees to Acorn Mobility Services, Ltd. and Acorn Stairlifts, Inc. under 35 U.S.C. § 285. The district court had deemed the case 'exceptional' due to Bruno's inequitable conduct in the prosecution of U.S. Patent 5,230,405. Bruno initiated a patent infringement lawsuit against Acorn in 2002, but during discovery, Acorn presented prior art that Bruno had failed to disclose to the Patent and Trademark Office (PTO), leading to the invalidation of the claims. The district court found that Bruno intentionally withheld the 'Wecolator' prior art while presenting it to the FDA, demonstrating intent to deceive the PTO. The appellate court affirmed the district court's findings, concluding that Bruno's conduct warranted the exceptional case status and justified the award of attorney fees. The court also upheld the denial of Acorn's request for additional discovery, finding no reversible error in the proceedings. Consequently, Bruno was ordered to pay $399,459.32 in attorney fees to Acorn, and the ruling was affirmed without granting Acorn's motion for double costs on appeal.
